Uses
demand paging with clustering. Clustering brings in
|
|
|
pages
surrounding the faulting page.
|
|
|
| • |
Processes
are assigned working set minimum (20-50) and
|
|
|
working
set maximum (45-345)
|
|
|
| • |
Working
set minimum is the minimum number of pages
|
|
|
the
process is guaranteed to have in memory.
|
|
|
| • |
A
process may be assigned as many pages up to its
|
|
|
working
set maximum.
|
|
|
| • |
When
the amount of free memory in the system falls below
|
|
a
threshold, automatic working set trimming is
|
|
|
performed
to restore the amount of free memory. (Balance

Working
set trimming removes pages from processes that
|
|
|
have
pages in excess of their working set minimum
